939082018-01-10Ionic Liquids Enabling Revolutionary Closed-Loop Life SupportCompletedOct 2016Jul 2017The innovation is to utilize ionic liquids with the Bosch process to achieve closed-loop life support. Specific tasks are to: 1) Advance the technology readiness of a proposed oxygen recovery life support technology to TRL 3, 2) To generate the data necessary to scale the proposed technology, and 3) To generate a system concept and basic designs.Development of a revolutionary implementation of the Bosch process using ionic liquids (IL) that can theoretically achieve 100% oxygen recovery save over a ton of mass resupply over a 3-year Martian surface mission. Life Support systems for long duration life support must be highly reliable, robust against environmentally-induced failures, and require limited resupply and crew interaction. An oxygen recovery system on ISS recovers ~50% of the oxygen from this CO2 and recycles it back to the crew, thereby reducing the required resupply of O2 from Earth. Future missions will require a minimum of 75% oxygen recovery with a target of >90% oxygen recovery from metabolic CO2 to limit resupply mass and logistical requirements.23332446Human Health, Life Support, and Habitation Systems32886.1Environmental Control and Life Support Systems and Habitation Systems37196.1.1Air Revitalization32457Human Exploration Destination Systems32937.1In-Situ Resource Utilization37417.1.3Processing and ProductionEarthThe MoonMarsCenter Innovation Fund: MSFC CIFSpace Technology Mission DirectorateMarshall Space Flight CenterMSFCNASA CenterHuntsvilleALAlabamaTherese GriebelWalter F Schneider
